Technology Uses Liquid Salt for Emissions Scrubbing

Less than a year after patenting a process that could improve stripping greenhouse gasses from industrial emissions, a University of Alabama engineering professor has been granted another patent that uses a different solvent to accomplish the same goal.

Assistant professor of chemical and biological engineering Dr. Jason E. Bara’s latest patent uses a form of liquid salt that could be swapped with chemicals currently used to scrub harmful emissions, such as carbon dioxide, from industrial emissions.

In a different patent granted in August 2013, Bara proposed switching currently used chemicals with a class of low volatility organic molecules. That patent was licensed by Ion Engineering in August. It is all part of his research focus of showing different, and possibly better, ways to capture harmful emissions.
